Direct Connection to a Computer

The printer is configured as Data Terminal Equipment (DTE).

This illustration shows the internal connections of the printer’s RS-232 connector.

Note • The cable used to connect the printer to a computer must be a null modem (crossover)

cable. To connect the printer to any other DTE devices, use a null modem cable.

Note • Pin 9 is also available as a +5 VDC power source at 750 mA. The maximum current

draw may be limited by option configuration. To enable this capability, a jumper on the

printer’s main logic board needs to be installed on JP1, pins 2 and 3.

NOTE: Pin 1 is unused and unterminated.
